There is a fishing trawler with a ladder leaning against a wall in the harbour. There are 5oars and two fishing nets in the trawler. The distance between two consecutive steps on the ladder is 1 meter. If the waves lashing against the wall rise a half meter in every half hour, in how much time will 6 steps of the ladder get under the waves???

The trawler rises with the waves so no step will go under water.

cad, or computer-aided design and drafting (cadd), is a software for design and technical documentation, which is an automated process as opposed to the manual drawing of plans. this gives a person an advance in making plans as an architect in a short period of time. one who can render plans through this software will gain a skill that is better than one who makes plans manually. this is a skill some companies look for in an employee.
